Just had the same thing after cleaning the oven. Mostlikely, the upper hinge on the left side of the oven door is out of alignment and not hitting the switch. Take the door off and gently bend the upper arm of the hinge inward and it should hit the switch. Otherwise, take of the left side panel (really easy, 6 screws) and you can see for yourself how the upper arm of the hinge hits/ should hit the swithch.

hello sir/mam
good you have changed the door seal but you cant do the wiring because if the wires are fully burnt it is difficult to notyfy which wire is connected to which part of the oven so please call the engineer he will do it.

Here is the service company I refer my appliance customers too!

If this dryer is 10 years old or more do not spend any money on it!
The new ones are much more efficient! If you have to replace it buy a Speed Queen , it will do 8 loads a week for 25 years!
It's the last washer and dryer I will ever buy!!!! And less expensive than a top of the line unit!

You will be fine now!

Mostly when you can light up the pits without the clicker, then that means that there is no power on the stove at all. Check the power cord running to it (which generate the sparks) and see if there is any damage to it.
